ride a traction power neeehanisin ot greater ethciency and which will he. more constant in its Work than has heen the ease with circuler traction Wheels heretotore used in such inai ehines.

l have selected :tor illustration and desoription e manure spreader :is typical of the rions mechanisms in Which nw iinpi'oveinents een he used. such n snr-'- comprising' a vehicle trarne. devices 'tor nro peiling; it. and two or more sets of driven parts on the traine treognentljv requiring; high power.

Referring' to the drawings in `which like numerals indicateV identical partsd Figure 1 is a side elevation ot a manure spreader with iny improved traction ineans attached.

livotally inounted on each end ot the att 2O are two triangular shaped trames between which are positioned flanged Aels 2li-4 25 and respectively mounted The hearings 27 t 2e are mounted adiustahly in in the traine Q3.

Adjacent the hearing 2i. und secnred'to the shatt 9;() hy nieans ot e. pin 50 is a clutch ineniher 5l lin'vingi; ratchet teeth 52 and a flange 53 inw? therewith.

' Between the clutch members 5l and 55 and held from longitudinal movement by the langes and 5o are clutch release members 6l :and 62 having on onevside cam sin-faces 63 and 64 adapted when in working yposition to mesh with each other to allow the teeth 52 and 57 of the clutchn'ieinbers to engage. The clutch release member (Si is held from rotatingkby means of a lever (i5 to which is attached a rod G6 which extendsto the 'forH ward end of the spreader where it is att-,ached to a lever (not shown) within convenient reach of the operator. The throwout mem ber 62 is held from rotating); by means of a bar 67 attached at one end to the member 62 by a rivet 68 and at the other end to the frame 15 by `a bolt- 69. It thus will be evident that by operating the lever by means of the rod 66 the member 6l. will be rotated and by reason of the cain faces 63 and 64 the clutch members 51 and 55 willvbetorced apart and the teeth 52 and 57 will be disengaged and motion imparted to the shat't 2O willl not be transmitted to the beater lO through the sleeve 54 and the spiders as is the case when the teeth of the clutch members are in engagement.

Engaging with the ground and around the perlipheries of the wheels 24, 25 and 2Gv and the sprocket wheel 37 is an endless chain, tread, or track 70 having on its inn-er side recesses adapted to engage the teeth of the sprocket- 37 and when the spreader is drawn over the ground it will impart motion to the sprocket' and through it to the shaft 35 which in turn will operate the shaft 2O by means of the ratchet 4l, the gear 45 and the gearV 48.

It will be evident that the ratchet and dog' devices will forma differential mechanism between the two driving' members of the spreader and will allow the spreader to be freely turned in either direction without causing undue strain on the drivingl parts and will also permit the uspreader to be f backed without operating` the beater in the reverse direction.

Each chain or endless tread engages with the ground alongV an approximately horizontal line extended suiiiciently to secure high traction and to insurea constant transmis- A sioncf high power, and to maintain the driven parts on the frame in uniform action, they being liable to experience wide variations in the load to which they are subjected.

The ground contacting part ot each chain can have a vibratory movement relatively to.

tread is mounted so as to be bodily movable. The frame which immediately carries it is adapted to swing` in a vertical plane because ot' its hinge connection with the main-vehicle frame or body; And, as the hinge axis is the axis about which the countersha tt 35 swings, transmission oi" power from the tread is not interrupted during; its swinging movement.

rihe two chains are so disposed that they can move thus bodily independently ot each other to contorni to va riationsin the ground surface along the sides ot the machine, and as the airis about which the iframes 23 swing is located between the transverse vertical planes of the axes o1"- the wheels 24, the lower course of each ot has extended engagement with the ground so that there is no danger oit slippage.

While I have, above, specifically de.

scribed a manure spreading mechanism and my improved devices as combined therewith, I do not mean to be understood as limiting; their usevto such machines. They can be em'- ployed upon portable mechanisms oi' anv of numerous terms which aredrawn or propolled over, and while resting upon, the ground sur resting' upon and being guided by track rails) and which carry working parts re quiringr motive power to actuate them relatively to the cari'iyincj iframe.
